pitman arm orientation?

[saxart]

Simple question...

I replaced the steering gearbox on my '70 for a power box from Red Head and can't remember/want to confirm. Does the pitman arm point straight to the rear of the truck if the wheels are in the straight ahead position?

My plan is to find "center" on the steering box by rotating the steering wheel from "full lock" on one side, to full-lock on the other side then bring it to center, then install the pitman arm.

Does this all sound correct?
